Mets minor leaguers Jordany Valdespin and Cesar Puello are among 12 players to have accepted 50-game suspensions for violations of Major League Baseball's Joint Drug Prevention & Treatment Program in connection to Biogenesis, the league announced this afternoon.

The 12 players will not appeal the bans.

"We have and continue to support Major League Baseball's Joint Drug Testing program," the Mets said in a statement this afternoon.

Valdespin and Puello have released nearly identical statements.

Valdespin's statement:

"I have been notified by the Commissioner of Major League Baseball that I have been suspended for 50 games for violation of the Joint Drug Agreement. I have decided to accept this suspension and not exercise my rights under the Basic Agreement to appeal. I made certain errors in judgment during the 2012 season and I accept full responsibility for those errors. I look forward to regaining the trust and respect of the Mets’ organization, Mets’ fans and my family, and look forward to contributing to the Mets in 2014."

Puello's statement:

"Today, I was notified by the Commissioner of Major League Baseball that I have been suspended for 50 games for violation of the Joint Drug Agreement. Out of respect for the Mets’ organization, my teammates, and my family, I have decided to accept this suspension and not exercise my rights under the Basic Agreement to appeal. I made certain mistakes during the 2012 season and I accept full responsibility for those mistakes. I look forward to regaining the trust and respect of the Mets’ organization, Mets’ fans and my family, and ultimately helping the club win a championship."

Of the list of 14 players suspended this season, eight are currently represented by the ACES agency, including Valdespin and Puello. Four others switched agencies within the last year. Cruz switched from ACES today.

Valdespin, currently with Triple-A Las Vegas, had recently served a three-game suspension for a benches-clearing altercation. The utilityman was playing second base for Las Vegas. He hit .466 in 16 games with a 1.296 OPS.

He was optioned to Triple A on July 13 and angrily responded to the news in the Mets clubhouse at PNC Park, infuriating several teammates. He hit .188 in 144 plate appearances for the Mets.

Unlike Puello, Valdespin had not been linked to Biogenesis publicly in the past. Puello was first connected to Biogenesis in March and went on to have a standout season with Double-A Binghamton. The outfielder hit .328 with 16 home runs, 24 stolen bases and a .955 OPS.

Alex Rodriguez was suspended 211 games through the 2014 season in a separate announcement. He is expected to appeal the suspension. Ryan Braun of the Brewers did not contest a 65-game suspension issued last month.

"The Union’s members have made it clear that they want a clean game," Major League Players Association Executive Director Michael Weiner said in a statement. "They support efforts to discipline players, and harshly, to help ensure an even playing field for all. The players support the Union’s efforts to uphold the JDA while at the same time guaranteeing that players receive the due process rights and confidentiality protections granted under the agreement."

The league also announced that Blue Jays outfielder Melky Cabrera, Athletics pitcher Bartolo Colon and Padres catcher Yasmani Grandal will not receive additional discipline after already serving 50-game suspensions as a result of their violations of the Joint Drug Prevention and Treatment Program stemming from their connections to Biogenesis.

The league ruled its investigation found no violations by either Nationals pitcher Gio Gonzalez or Orioles infielder Danny Valencia after they had been connected to Biogenesis.
